ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 413,062, dated October 15, 1889.

Application filed March 15, 1889- Serial No. 303,387. (No model.)

To all whom it may concern:

Be it known that I, LYMAN D. HOWARD, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and usefulImprovement in Elevator- Buckets, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in to elevator-b uckets; and it consists, first-,in providing the same with a pivoted bottom having an extension, a catch adapted to bear against said extension, and means, substantially as described, for disengaging the said catch from the extension, so that the bottom may be opened.

It further consists of the combination and arrangement of parts, as herein described and claimed.

Figure 1 represents a side elevation of an elevatorbucket embodying my invention. Fig. 2 represents a rear View thereof.

Similar letters of reference indicate corre' sponding parts in the two figures. Referring to the drawings, A designates an elevator-buoket, which is connected with the elevator-chains B, which features in general respects are ofusual construction.

O designates the bottom of the bucket, the same being pivoted to the lower end of the bucket, as at 0, so as to open downward.

D designates a rear extension of the bottom, against whose upper side rests the heel E of a vertically-arranged catch F, the latter being pivoted to the rear of the bucket, and having the upper ends of its side bars formed with swells or deflectors G, which project rearward and are adapted to engage with a roller or abutment H on the standard J of 4c the elevator-frame.

The operation is as follows: The feet E pre vent ascent of the rear extension of the bottom 0 and consequent descent of the latter, whereby the contents of the bucket are retained within the same. When the bucket is elevated and the deflectors G reach the roller H, they ride over the same, thus operating the catch F, whereby theheel or lower end thereof is moved from its engaging position on the part I) of the bottom, whereby the bottom is no longer controlled by the catch F, and as the weight of the contents of the bucket is superimposed upon said bottom the latter drops and thus opens, so that the contents are discharged, as is evident. "When the 5 bucket turns over the wheels of the elevator, the bottom assumes its normal position, the heel E having an inclined face, so that the part D rides freely over the same, after which the catch returns over said part by the action of gravity, and thus the bottom is again held or locked, so that the bucket maybe properly filled.

Having thus described my invention, what I claim as new, and desire to secure by Letter Patent, is

1. An elevator-bucket having apivoted bot tom with an extension, a catch adapted to bear against the said extension, and means, substantially as described, for disengaging said catch from said extension, said parts being combined substantially as described.

2. An elevator-bucket having its dropping bottom provided with a rearward extension and a catch pivoted to said bucket engaging With said extension, said catch having also a deflector, whereby the catch may be moved from engagement with the bottom, substantially as described.

' 3. An elevator-bucket having a dropping 8o bottom, a catch having a heel, and a deflector, said heel engaging with said bottom and formed with an inclined face, the deflector being adapted to engage with an abutment on the elevator-frame for clearing said heel from said bottom, substantially as described.
